RE has also posted 14HP gain at a certain point, although not 14 at the top. They are probably doing the same and just not specifying anything.

I'm thinking about the RE one since Chuck has said up front if it doesnt perform he will take it back.

 

Chuck, you mentioned a while ago that it costs big bucks to polish the heat shield. Would it be possible to get this intake with a black, non-polished heat shield, or possibly to retain the factory airbox cover, and save some money? I personally don't care that much how pretty it is, as long as it work as advertised!

Thanks...

 

Only the Mazdaspeed original parts come painted. Our fiberglass or urethane bodykit do not come painted. Sorry about that.

I am working on the carbon fiber and fiberglass headlight eyelids right now. They should be finished in about a week.

Thank you.

All the top covers I have are polished. I am sorry that I can't sell one without the polished top cover because aesthetics matters. It's just not good for us to sell a product that looks unfinished.

There is no factory air box cover. What you see is just the air box.

I am working with the site owner right now for advertisement. Once it's set up, I will host a group buy on the intake if there is enough interest. Sounds good?

Chuck Huang

 

I would be interested in a group buy Chuck, and it will be great to see these eyelids. Keep up all the great work!

BTW, why did you keep the accordian. I noticed that K&N Typhoon intake removed it. Perhaps for a deeper noise ?

 

Chuck - I'd be interested in a group buy for the short-ram CAI, and would really like to see your carbon fiber cover. Woudl you offer a 'core exchange' for exchanging the polished cover to carbon fiber?

Thanks!

 

Hope I did not appear to be 'smart', I work on the PC all day, and sometimes I miss words cause I get so cross-eyed! :-)

 

I think with Chuck you are going to have better service - your dealing with him directly - K&N - well theres all that phone crap and so on. The only think you buy from K&n is probably the name and quality of the product. ( my 3.5 cents worth )

 

Yep, I'd be interested in a group buy too.

 

Interest here too for a group buy.

 

Yes, I am also would be interested in group buy. What would be my total cost for shipping to Toronto - Canada including dutie fees?

Great Work!!!

 

There are a lot more things to consider other than how much hp its going to produce. You also have to think about MAF readings and turbulance in the intake path. You also don't want it to make the engine run to lean, because that is how it makes power. If it does you could be looking at detonation. Does anyone know how the K&N unit is mounted in the engine bay? Also I have seen intakes make 12hp before so dont doubt them. I have a K&N cold air in my wrx and it works great.

 

Group buy sounds good to me

 

Most intake systems these days use K&N filters. Their design is no different than most of the systems that will be coming out for the RX-8, unless it is routed down into the bumper. Its possible you can pick up 12HP from an open intake. Im sure AEM and Injen will come out with an intake, but its going to do the samething as all the others with similar HP claims. Putting the intake in its own box or cover isnt going to add much HP over than keeping it open.
K&N typically sells to retailers. You should be able to order it from any authorized K&N dealer when it comes out.

got any links to RE intake?

 

me too me too

 

I'm interested in group buy too

 

Please post the raw data from the dyno please.

Chuck, two questions before I decide on buying it:
Does this void the warranty? I'm assuming no.
Does it enhance the sound of the engine?
Thanks.

 

I think if it did void the warranty it could easily be removed. Some Mazda dealerships are more picky than others it seems

 

Chuck was nice enough to forward the site below concerning warranty issues.

As to the sound of his unit, he also responded:

"Because the intake is open element so it's going to be louder than stock only if you accelerate. If you are only cruising, it will not be louder"

I don't know about tuned intake ports and supersonic swirls etc, but I wonder if some of us give too much credit to the OEM design. They have to deal with so many compromises, cost, noise rules, EPA rules, filter efficiencies.... My limited experience with motorcycles indicates (rented dyno time proven) there is power to be had with playing with OEM intakes. Sure, the RX8's looks pretty good, but folks like Rotary Extreme can provide dyno results showing improvements. I have ordered one of Chuck's units to test. We shall see.

I keep the tube because I found it makes no HP gain replacing it with a silicone transition hose which costs $40. Besides that, the stock one comes with a chamber that muffles the sound a bit so the intake is not as loud. With the current setup, the sound from the intake is the same as stock when you cruise and you can really hear it when you floor it. I figure this is the best for rx8 which should be civilized when you just drive around town and cruise.

Thank you.

Dynosheet has been posted in this thread. What raw data do you need? The dyno numbers were SAE corrected just in case you are wondering about the ambient temp and humidity.

what about the group buy
any options?
